The two features at issue here — the discourse particle like and “uptalk” (a high rising intonation at the end of declaratives) — have been much discussed in the linguistic literature. The popular, but inaccurate, perception is that both are characteristic of young people, especially teenagers, especially girls, and both features are the object of much popular complaint.

The slang in the body of the strip — airdog, boned out, shred, shred the gnar, pop, nollie, pow-wow — is all genuine snowboarder slang, listed in the enormous collection of snowboarding terms here. The title, “Shagnasty”, is slang, but apparently not slang specific to snowboarding.

The theme is that women — especially, teenaged girls — talk talk talk, in a rapid, never-ending stream, one sentence flowing into the next, one story into the next, without pause. You can’t get a word in edgewise, the saying goes. (The truth is far from this, of course.)

But Jeremy has found the solution, a very satisfying one: the punctuational kiss.

This is the latest in a series of strips about Jeremy and Sarah: Jeremy seems not to be listening to Sarah at all (and Jeremy’s father is presented as doing the same to Jeremy’s mother), and now, when Jeremy responds, it’s in monosyllables — he’s speaking, but not communicating.

That gives us two stereotypes at once: genderspeak and teenspeak. Males don’t listen, males are uncommunicative (especially when talking to females), and the teen stereotypes are for “laconic guys and gabby guys”.

In the strip above, Jeremy finally produces a minimally non-monosyllabic response. I doubt that it will satisfy Sarah.

Here we have a deliberately uncooperative response from Jeremy, who treats his mother’s request entirely literally, rather than thinking “Why is she making this request?” and calculating the reasons for her request and the kind of response she’s looking for. So his answer flouts Grice’s Maxim of Relation (or Relevance), as in this discussion of an earlier Zits. Jeremy is given to evasive uncooperativeness.

Note Jeremy’s facial expression in the first panel, and both facial expressions in the third.

Today’s Zits — with Jeremy talking so fast his mother can’t understand what he’s saying — turns out to be a repeat performance; I posted about this strip on Language Log in 2009, under the title “Teen speech in overdrive”.

Jeremy’s mother: “Can’t you just talk slower?” Jeremy: “Can’t you just listen faster?”
